IVM. CHADVICK AND S. J. B. ANDERSON, OF TERRE HAUTE, INDIANA.

RAILROAD DITCI-IING-JNIACHNE.

Specification of Letters Patent No.

To all whom i may concern:

Be 1t known that we, WM. CHADwIoK and i S. J. B. ANDERSON, both of TerreHaute,

in the county of Vigo and State of Indiana, have invented a new anduseful Railroad Ditching-Machine; and we do hereby declare that the sameis described and represented in the following specification anddrawings.

To enable others skilled in the art to make and use our invention wewill proceed to describe its construction and operation referring to thedrawings in which the same letters indicate like parts in each of thefigures.

Figure l, is an elevation of one side of the machine. Fig. 2, is a planof the machine, the top frame on the right hand half being omitted toshow the parts below more clearly.

The nature of our invention consists in a series of levers arranged upona railroad car, and extending over the sides and arranged to hold andoperate scoops or scrapers, to take the earth from the sides of the railtrack to make a ditch by the side of the railroad on which the car runsthat carries the levers. Also in making the scoops or Scrapers so thatthey can be worked either end forward, the same side up to be filled.Also in making a vibrating mouth piece to the scrapers that can beworked, so as to aid in loading the scraper.

In the accompanying drawings A, is the body or top of a railroad carmounted on the trucks B, B, so as to travel, or run on a rail road ofordinary construction. C, C, are two bars-fastened on the top of eachend of the car, into which bars the posts D, D, are fastened to supportthe top frame E., as shown in the drawing. There are ten lleversnumbered from l, to l0, fastened to the car A, with eye bolts so as tovibrate freely the ends of tive of these levers project from one side ofthe car and the ends of the other five project from the opposite side asshown in Fig. 2. The ditching scoops F, F, are hung to the levers 7, and9, by chains as shown in Fig. l, and the scoop F, is connected to thelevers 6, and 8, by iron rods or bails G, G, and the scoop F', to thelevers 8, and 10, by chains Gr', G. The levers 2, 4, 7, and 9, areprovided with pulleys H, H, for the ropes I, I, which are fastened tothe top frame E, and pass under the pulleys H, H, on the levers to(raise them) and over 21,942, dated November 2, 1858.

pulleys in the top frame E, and are fastened to the rollers J, J, whichare arranged to turn in hangers K, K, fastened to the top frame E. Therollers J, J, have the large pulleys M, fastened to them; to whichpulleys the ropes N, N, are fastened; the other or opposite ends ofthese ropes are fastened to the shafts 0, C, which shafts are providedwith cranks I), l), and are arranged to turn in standards Q., Q, fromthe frames l, R, fastened to the body A. The shafts O, O, are providedwith ratchet wheels S, S, and pawls T, T that are arranged to vibrate,so that when they are in the position shown at U, they catch the teethof the wheels S, and hold it; but by drawing them into a perpendicularposition, right opposite the standard Q, the ratchet wheel will bereleased and may be turned back to unwind the rope on the shaft O, andlet down the scoop.

The levers l, 3, 5, 6, 8, and 10, have ropes V, V, fastened to them neartheir outer ends which ropes pass over pulleys in the top frame E, so asto be pulled by the attendant, and raise the end of the scoop attachedto the lever, and depress the opposite end, so that it will catch theearth, as the car is drawn along on the road, and hold the earth socaught, until the car arrives where the earth taken up by the scoop isto be deposited; when the scoop may be emptied by raising it so nearperpendicular that the earth will slip out.

The scoops F, and F', are made in the form shown in the drawing, that iswith curved bottoms and both ends alike, so that they will catch the.earth with the same facility, when the car moves them in eitherdirection.

It is a great advantage to make the scoops, so that they can be filledat either end, as one end of the scoops can be filled when moving in onedirection and the other end when moving in the opposite direction, andin this way both ends can be filled with facility with a much largerload than if they were filled at one end only.

rlhe bars C, C, frames R, R, and bars W, lV, are so arranged on the bodyA, as to prevent the levers from swinging sidewise when working thescoops.

To use'this machine the operator adjusts the scoops to the desiredheight by turning the cranks P, l?, then by pulling the ropes V, V, toraise one end of the scoops and los depress the other end, to catch theearth and load one end of the scoop, and while doing so, he can turn thecrank P, and lower the scoop while it is being lilled and after y it isfilled 'raise it again to carry the load to the place of deposit; andwhen it arrives there one end may be raised without stopping the car soas to empty and deposit the load as may be desired.

Should it bc desirable to do so one of the scoops may be removed and oneor more plows put in its place to plow the earth and prepare it for thescoop; or instead of the plows chains may be applied to take up stonesstumps or other articles that require to be removed from the side of theroad.

Fig. 3, is a plan and elevation of a scoop with a vibrating mouth pieceX, hinged to the bottom of the scoop. This mouth piece has perpendicularsides to which the bail Y, is attached, and there is a slot Z in oneside for a bolt which limits the vibrations of the mouth piece. The armZ is fastened to one side of the mouth piece to enable the operator towork it up and down as he desires.

Ve believe we have described and represented our invention, so as toenable any person skilled in the art to make and use it.

We will now state what we claim and desire to secure by Letters Patentto wit:

l. 7e claim the levers 2, t, 7 and 9, arranged on a car substantially asdescribed for holding the scoops at the side of the car and foradjusting or raising and lowering them as required.

2. 7e also claim the levers l, 3, 5, 6, 8 and 10, arranged on a railroadcar as described, for operating the scoops so as to catch their load ofearth and for dumping them as required.

8. `We also claim the scoops F F made as described so that they may beworked either end forward the same side up to be lilled.

4. `We claim the vibrating mouth piece X, hinged to the scoop so as tobe vibrated substantially as described.
